We want to share more alert and application data handling code.
Some of the application data handling code, packet handling,
will not be relevant for dtls, but this code can be excluded from dtls
by options checking.

ssl_handshake:update_handshake_history
This proably a much bigger problem for DTLS than TLS, but should be
disabled for both unless explicitly configured for TLS.
|
|
When protocol version is proagated from the DTLS connection processes
state into general ssl functions it must be converted to the corresponding
TLS version.

The callback is invoke before entering state 'connection'.
It allows a connection module to remove data from the
connection state that is no longer needed (e.g.
handshake history).

Moving a fun into a guard may cause code that is not accepted

* bjorn/floor-ceiling/OTP-13692:
Add math:floor/1 and math:ceil/1
Implement the new ceil/1 and floor/1 guard BIFs
|
|
Add math:floor/1 and math:ceil/1 to avoid unnecessary conversions
in floating point expressions. That is, instead of having to write
float(floor(X)) as part of a floating point expressions, we can
write simply math:floor(X).
|
|
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of
Erlang language). They are guard BIFs because trunc/1 is a guard
BIF. It would be strange to have trunc/1 as a part of the language, but
not ceil/1 and floor/1.

ssh_msg_userauth_info_request
This behavour is assumed by Codenomicon Defensics.
|
|
This is needed when running programs that only exit when
stdin has been closed, e.g. 'more'.
|
|
Even though v2 is never supported v2 hellos can be.
No support for v2 client hellos gives "handshake failiure" alert.
Support for v2 hello but no higher SSL/TLS version offered
gives "protocol version" alert.

Also correct algo_cipher[] size since it was one to small.

If temps introduced by hipe_regalloc_prepass end up above SpillLimit,
the register allocators will not spill them. This constraint is
unnecessarily limiting the allocators and might theoretically lead to
unallocatable programs (more temps above SpillLimit alive at a time than
there are physical registers).

These will not only be useful for hipe_regalloc_prepass, but also, after
the introduction of a mk_move/2 (or similar) callback, for the purpose
of range splitting.
Since the substitution needed to case over all the instructions, a new
module, hipe_ppc_subst, was introduced to the ppc backend.

Since the substitution needed to case over all the instructions, a new
module, hipe_x86_subst, was introduced to the x86 backend.
Due to differences in the 'jtab' field of a #jmp_switch{} between x86
and amd64, it regrettably needed to be duplicated to hipe_amd64_subst.
|
|
Now that all backends do register allocation on a CFG directly and
define the defun_to_cfg/1 callback as the identity function, it can be
removed.
|
|
As the just_as_good_as assertion was loosened with the `NowRegs >=
CheckRegs` check, it no longer verified that hipe_regalloc_prepass had
not incorrectly labeled a temp as unallocatable. We add that behaviour
back.
|
|
|
|
This is due to the improvements in hipe_temp_map, removing the need for
duplicated logic in the backends.

hipe_regalloc_prepass speeds up register allocation by spilling any temp
that is live over a call (which clobbers all register).
In order to detect these, a new function was added to the target
interface; defines_all_alloc/1, that takes an instruction and returns a
boolean.

The filters in a list comprehension can be guard expressions or
an ordinary expressions.
If a guard expression is used as a filter, an exception will basically
mean the same as 'false':
t() ->
L = [{some_tag,42},an_atom],
[X || X <- L, element(1, X) =:= some_tag]
%% Returns [{some_tag,42}]
On the other hand, if an ordinary expression is used as a filter, there
will be an exception:
my_element(N, T) -> element(N, T).
t() ->
L = [{some_tag,42},an_atom],
[X || X <- L, my_element(1, X) =:= some_tag]
%% Causes a 'badarg' exception when element(1, an_atom) is evaluated
It has been allowed for several releases to override a BIF with
a local function. Thus, if we define a function called element/2,
it will be called instead of the BIF element/2 within the module.
We must use the "erlang:" prefix to call the BIF.
Therefore, the following code is expected to work the same way as in
our second example above:
-compile({no_auto_import,[element/2]}).
element(N, T) ->
erlang:element(N, T).
t() ->
L = [{some_tag,42},an_atom],
[X || X <- L, element(1, X) =:= some_tag].
%% Causes a 'badarg' exception when element(1, an_atom) is evaluated
But the compiler refuses to compile the code with the following
diagnostic:
call to local/imported function element/2 is illegal in guard

The compiler would crash in v3_codegen when trying to compile the
following code:
is_port(_) -> false.
foo(P) when port(P) -> ok.
We *could* have the compiler interpret the code as:
is_port(_) -> false.
foo(P) when erlang:is_port(P) -> ok.
But that would encourage using the obsolete form of the guard tests.
Note that the following code is illegal:
is_port(_) -> false.
foo(P) when is_port(P) -> ok.
It produces the following diagnostic:
call to local/imported function is_port/1 is illegal in guard
Therefore, we should refuse to compile the code.

SSH sends the public key and user name twice. If we do not

will complain.
